Lub neej hacker nkag siab txog dab tsi yog qhov peculiarity ntawm OLED TVs, thiab pom tias qhov twg nws yog qhov zoo dua los xaiv ib qho screen OLED.

Vim li cas OLED technology nthuav?

OLED (organic light emitting diode) yog hu ua lub neej yav tom ntej ntawm TV thev naus laus zis, uas cog lus cov xim nplua nuj, suav nrog cov xim dub tob, thiab txo cov suab nrov plooj.

Tej zaum nws yuav zoo li hais tias cov cuab yeej tshiab tsis txawv ntau ntawm cov LED vaj huam sib luag ntau dua ntawm kev ua lag luam. Tab sis lo lus "organic" txhais tau hais tias qhov sib txawv ntawm txoj kev cov duab tau nthuav tawm ntawm qhov screen.

Dab tsi yog qhov zoo ntawm OLED cov ntxaij vab tshaus?

LED npo - Cov kua siv lead ua kua zaub nrog txhim kho LED backlighting. Nyob rau hauv niaj hnub LCD TVs, kua muaju tig nyob rau hauv lub zog ntawm hluav taws xob thiab xa lub teeb los ntawm txhua pixel nyob rau hauv daim duab. Lub teeb dhau los ntawm cov ntxaij lim dej (liab, xiav thiab ntsuab) thiab thaum sib xyaw, ua rau cov xim xws li tsaus nti mus rau dawb. Yog hais tias tag nrho cov muaju yog tig kom tsis txhob nco ib qho ntawm peb xim, ces cov zis yog dub.

Crystals muaj lawv tus kheej zoo: tus nqi qis, thinness thiab lightness ntawm cov ntaub ntawv, tab sis kuj muaj ib qho tseem ceeb drawback - theem ntawm cov xim dub. Cov crystals thaiv lub teeb, tab sis lub teeb backlight tseem ua haujlwm. Lub teeb poob rau ntawm "dub" pixels, uas ua rau cov duab tsaus nti.

OLED cov ntxaij vab tshaus tsis muaj lub teeb rov qab - txhua tus pixel emits lub teeb ntawm nws tus kheej thaum muaj hluav taws xob siv rau nws. Yog tias lub pixel tsis tau txais hluav taws xob, ces peb pom qhov tsis muaj lub teeb - dub tiag tiag.

Tsis muaj pes tsawg tus nqi rau xim thiab ci ci hloov qhov kev nkag siab ntawm qhov sib txawv. Ntawm OLED zaub, txawm tias qhov tsawg tshaj plaws ntawm lub teeb nyob rau hauv qhov tsaus ntuj ntawm daim duab pom tau tias ci dua li cov duab LED. Tsis tas li ntawd, cov pixels hauv OLED cov ntxaij vab tshaus tuaj yeem hloov xim yuav luag tam sim, tsis zoo li lub lag luam ntawm LED vaj huam sib luag, uas siv sijhawm ntev dua los qhib thiab txav cov muaju.

Lwm qhov zoo dua ntawm OLED thev naus laus zis, uas tau txais los ntawm qib dub thiab qhov sib txawv, yog cov xim saturated tiag tiag.

Puas yog pixels hlawv tawm ntawm OLED cov ntxaij vab tshaus?

Nyob rau hauv cov laus plasma TVs, pixels yuav hlawv tawm nyob rau hauv cov qhov chaw ntawm lub screen qhov twg ib yam dab tsi zoo li qub nyob rau lub sij hawm ntev, xws li ib tug channel logo los yog ib tug video game menu. Cov kab los ntawm cov khoom zoo li no tuaj yeem "ntim" mus tas li ntawm cov zaub, yog li cov tuam ntxhab ntxiv cov cuab yeej tshwj xeeb rau TV teeb tsa kom tsis txhob muaj qhov no.

Qhov no tsis zoo rau OLED cov ntxaij vab tshaus, tab sis yog tias daim duab zoo li qub tau tso tseg rau ob peb teev ua ke, ces nws tuaj yeem "khov", tawm hauv qhov pom tsis tshua pom, txog li ib teev, thiab tom qab ntawd ploj tag. Tsis muaj dab tsi phem yuav tshwm sim rau TV.

OLED cov duab ci li cas?

Yog tias lub TV muaj daim ntawv nplaum Ultra HD Premium, ces nws cov pixels yuav tsum ncav cuag qhov ci ntsa iab yam tsawg kawg nkaus. Tus nqi no tuaj yeem sib txawv nyob ntawm qhov tob ntawm cov xim dub. Yog tias qib dub hauv OLED vaj huam sib luag yog qhov chaw ntawm 0.005 thiab 0.5 cd / m2², ces qhov siab tshaj plaws brightness rau xws li TV yuav tsum pib ntawm 1,000 cd / m2²… Tab sis yog tias lub vijtsam muaj peev xwm ntawm cov xim tsaus dua, ces nws qhov siab tshaj plaws tuaj yeem pib los ntawm 540 cd / m2.².

Qhov ci ntsa iab ntawm OLED TV tau pom nyob ntawm qhov chaw koj tso nws, yog li hauv chav ci ci qhov txiaj ntsig ntawm OLED screen yuav tsis pom. Pheej yig OLED panels xa 700-800 cd / m2 ci ntsa iab², thaum LED TVs muaj peev xwm ntau dua - 1,400-1,500 cd / m2².

Tshiab OLED TVs yuav los rau xyoo no nrog qhov ci ntsa iab txog 2,000 cd / m2², tab sis lawv cov nqi tsis zoo li yuav txaus siab rau cov neeg yuav khoom.

Nrog lub siab tshaj plaws screen brightness ntawm 800 cd / m2² nws qhov zoo dua LCD TVs pom thaum hmo ntuj hauv lub teeb qis lossis nruab hnub nrog cov ntaub thaiv kaw. Thaum lub teeb dimmed, cov nyhuv ntawm cov xim dub ntawm cov duab zoo yuav pom tseeb.

Txawm li cas los xij, cov dub tob tsis yog cov khawv koob uas hloov cov yeeb yaj kiab ntawm qhov screen. Qee zaum, piv txwv li hauv cov kev pabcuam streaming, dub tuaj yeem nkag mus tsis yog qhov tsis muaj lub teeb, tab sis raws li nws cov qauv sib dua.

Raws li nrog cov xim rendering zoo, cov lus tsa suab plooj txo yog nyob ntawm cov ntsiab lus qub. Hauv txoj kev xav, OLED thev naus laus zis tshaj LCD thiab LED cov qauv rau kev sib kis.

Hauv kev xyaum, tsuas yog cov ntaub ntawv tshwj xeeb uas tau npaj tseg thiab qhov kev txo qis qhov muag plooj ua cov txiaj ntsig pom. Dynamic movies nrog tus nqi duab ntawm 24 ntas ib ob yuav tsis ua hauj lwm. Nyob rau tib lub sijhawm, nws yog qhov nyuaj heev los nrhiav 4K video, nrog cov xim tiag tiag thiab tus nqi siab nyob rau tib lub sijhawm, kom pom tseeb qhov kev yuav khoom ntawm OLED vaj huam sib luag kim.

Yog tias koj tseem xav koom nrog lub ntiaj teb ntawm HDR, ces qhov no nws yog qhov zoo dua los xaiv lub vijtsam OLED, tab sis koj yuav tsum ntsuas nws kom raug. Rau cov chav loj, xws li TVs tsis muaj txiaj ntsig los yuav yog tias koj muaj ntau dua $ 20,000 rau 77-nti LG qauv.

Qhov qis plooj thiab vibrant xim ntawm OLED panels kuj zoo rau kev ua si, tab sis xav txog cov tswv yim lag luam ntau dua, uas cuam tshuam rau kev teb thiab tshwj xeeb yog qhov tseem ceeb hauv kev ua si hauv online. Cov neeg tsim khoom tau pib daws qhov teeb meem no nrog kev hloov kho firmware.
